Introduction

Mental health problems during pregnancy and the postpartum period are common, affecting up to 20% of women. These conditions can include depression, anxiety, obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), and in some cases, postpartum psychosis. Early identification and management are crucial to ensure the well-being of both the mother and the baby.

Common Mental Health Conditions

The most common mental health conditions that can affect women during pregnancy and the postpartum period include:

Depression

• Antepartum Depression: Depression that occurs during pregnancy. Symptoms include persistent sadness, loss of interest in activities, fatigue, and feelings of worthlessness.
• Postpartum Depression (PPD): Depression that occurs after childbirth, usually within the first year. Symptoms are similar to antepartum depression but may also include difficulty bonding with the baby, excessive worry about the baby's health, and thoughts of self-harm or harming the baby.

Anxiety Disorders

• Generalised Anxiety Disorder (GAD): Characterised by excessive worry about various aspects of life, including the pregnancy, childbirth, and the baby's health.
• Panic Disorder: Recurrent panic attacks that may involve palpitations, shortness of breath, and fear of losing control. This can be particularly distressing during pregnancy.

Obsessive-Compulsive Disorder (OCD)

• OCD can worsen during pregnancy or postpartum. Common obsessions include fears about harming the baby or concerns about cleanliness and germs, leading to compulsive behaviours.

Post-Traumatic Stress Disorder (PTSD)

• PTSD may be related to previous trauma or traumatic experiences during childbirth. Symptoms include flashbacks, nightmares, and severe anxiety.

Postpartum Psychosis

• A rare but severe mental health condition that typically occurs within the first two weeks after childbirth. Symptoms include hallucinations, delusions, confusion, and rapid mood swings. It is a medical emergency requiring immediate intervention.

Impact on Mother and Baby

Mental health problems during pregnancy and postpartum can have significant impacts on both the mother and the baby:

• For the Mother: Increased risk of poor self-care, substance misuse, difficulty bonding with the baby, and suicide in severe cases.
• For the Baby: Increased risk of preterm birth, low birth weight, and developmental issues. Babies of mothers with untreated mental health conditions may also experience attachment issues and emotional difficulties later in life.

Management

The management of mental health problems during pregnancy and postpartum involves a multidisciplinary approach, including psychological therapies, pharmacotherapy, and social support:

Psychological Therapies

• Cognitive Behavioural Therapy (CBT): Effective for treating depression and anxiety during pregnancy and postpartum. CBT helps individuals identify and change negative thought patterns and behaviours.
• Interpersonal Therapy (IPT): Focuses on improving interpersonal relationships and social functioning, which can be particularly beneficial for women experiencing postpartum depression.
• Mindfulness-Based Therapies: These therapies can help manage anxiety and stress during pregnancy by promoting relaxation and present-moment awareness.

Pharmacotherapy

• Antidepressants: Selective serotonin reuptake inhibitors (SSRIs) are commonly used, with careful consideration of the risks and benefits during pregnancy. The choice of medication and dosage should be individualised.
• Anxiolytics: Benzodiazepines may be used short-term for severe anxiety or panic attacks, but their use in pregnancy is generally limited due to potential risks.
• Antipsychotics: May be necessary for managing severe conditions such as postpartum psychosis, with careful monitoring of both mother and baby.

SSRI Safety in Pregnancy

Selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed for depression and anxiety during pregnancy. The safety of SSRIs in pregnancy has been extensively studied, and while there are some potential risks, these must be weighed against the risks of untreated maternal mental illness:

• Fluoxetine: One of the most studied SSRIs in pregnancy. It is generally considered safe, although there may be a slightly increased risk of congenital malformations if used in the first trimester. It is also associated with a small risk of persistent pulmonary hypertension of the newborn (PPHN) when used later in pregnancy.
• Sertraline: Often preferred in pregnancy due to its favourable safety profile. Studies suggest it has a lower risk of adverse outcomes compared to other SSRIs.
• Citalopram and Escitalopram: These SSRIs are generally considered safe, though there may be a slightly increased risk of congenital heart defects with high doses.
• Paroxetine: Generally avoided in pregnancy due to an increased risk of congenital heart defects when used in the first trimester.

It is important to monitor the mother and baby closely if SSRIs are used during pregnancy, especially near delivery, as there is a risk of neonatal adaptation syndrome, which can include symptoms such as irritability, respiratory distress, and feeding difficulties.

When to Refer to Perinatal Mental Health Services

Referral to a specialist perinatal mental health service is recommended in the following situations:

• Severe or Complex Mental Health Problems: If the patient presents with severe depression, anxiety, OCD, PTSD, or any signs of postpartum psychosis, a referral should be made urgently.
• History of Severe Mental Illness: Women with a history of bipolar disorder, schizophrenia, or severe depression should be referred early in pregnancy for specialist care.
• Inadequate Response to Initial Treatment: If the patient does not respond to initial management in primary care, referral to a perinatal mental health team is necessary for further assessment and treatment planning.
• Medication Management: If there are concerns about the safety or appropriateness of medication during pregnancy, specialist advice should be sought.
• Risk of Harm: If there are concerns about the mother’s safety or the safety of the baby, immediate referral to specialist services is required.
